Abstract Salt caverns have been successfully used for natural gas storage globally since the 1940s and are now under consideration for hydrogen (H2) storage, which is needed in large quantities to decarbonize the economy to finally reach a net zero b

An increasing number of oil and gas companies reach their economic limit after years of production, exhausting the support of natural-pressure drive mechanisms in the reservoir and the benefits of water or gas injection [...]

Microorganisms can produce bio-hydrogen (H2) during their metabolism, and especially dark fermentative production from carbohydrates is a promising option. However, the technology still suffers from low H2 production rates due to product inhibition o

Polymer flooding has been a successful EOR method in sandstone reservoirs for decades. Extending polymer flooding to carbonate reservoirs has been challenging due to adsorption loss and polymer availability for high temperature, high salinity (HTHS)

Polymers are attractive enhanced oil recovery (EOR) chemicals that improve sweep and accelerate production. There is an ongoing search for polymers that are more temperature-, salinity-, and shear-stable as fields in increasingly challenging environm

A method for characterising water and oil in a rock core plug using correlations between diffusion decay in internal magnetic gradient and transverse relaxation time ( DG 0 2 - T 2 ) is presented. The method is evaluated at different saturation level

Hydrophobically modified polyacylamides (HMPAMs), also known as associative polymers, have high potential as EOR chemicals due to their specific chemical properties. However, the strength of hydrophobic interactions also leads to more complex flow be

Polymer flooding has increasingly been considered for heavy oil recovery applications. This has been encouraged by positive results from field applications at e.g. Pelican Lake and Tamaredjo and lab experiments showing that highly efficient recovery

In the method Decay due to Diffusion in the Internal Field (DDIF), the diffusion behaviour of water molecules in the internal magnetic field makes it possible to determine a distribution of pore sizes in a sample. The DDIF experiment can also be exte

Ideally, in a chemical flooding process, one would like to inject a surfactant solution that has good solubility at the relevant conditions, ultralow interfacial tension (efficient oil mobilisation) and low loss of surfactant (better economics) in th
